In fact, LED is still energy-saving. The measurement standard depends on its light efficiency.

The unit of light effect is "lumen/watt". That is to say, how many lumens of luminous flux each watt of electrical power can be converted into. As an incandescent lamp, it is about 15 lumens per watt, and a fluorescent lamp is 60-90 lumens, while the market-oriented LED has reached nearly 200 lumens per watt (higher in the laboratory). Therefore, under the premise of achieving the same lighting effect, LED can save more than half of the electric energy, and the energy-saving effect is obvious.";s:6:"filter";b:1;s:6:"visual";b:1;s:22:"so_sidebar_emulator_id";s:14:"text-402210000";s:11:"option_name";s:11:"widget_text";s:11:"panels_info";a:7:{s:5:"class";s:14:"WP_Widget_Text";s:3:"raw";b:0;s:4:"grid";i:0;s:4:"cell";i:0;s:2:"id";i:0;s:9:"widget_id";s:36:"3c621377-cfee-4e66-bde6-bda7f9251516";s:5:"style";a:2:{s:27:"background_image_attachment";b:0;s:18:"background_display";s:4:"tile";}}}i:1;a:17:{s:5:"image";i:4015;s:14:"image_fallback";s:0:"";s:4:"size";s:4:"full";s:5:"align";s:7:"default";s:11:"title_align";s:7:"default";s:5:"title";s:0:"";s:14:"title_position";s:6:"hidden";s:3:"alt";s:0:"";s:3:"url";s:0:"";s:12:"_sow_form_id";s:32:"108020681463ec7fe4b11ca646913495";s:19:"_sow_form_timestamp";s:13:"1676443643746";s:11:"panels_info";a:6:{s:5:"class";s:30:"SiteOrigin_Widget_Image_Widget";s:4:"grid";i:0;s:4:"cell";i:0;s:2:"id";i:1;s:9:"widget_id";s:36:"700d67e9-6c8e-4bec-84fd-123618eec8b8";s:5:"style";a:2:{s:27:"background_image_attachment";b:0;s:18:"background_display";s:4:"tile";}}s:10:"new_window";b:0;s:5:"bound";b:0;s:10:"full_width";b:0;s:22:"so_sidebar_emulator_id";s:19:"sow-image-402210001";s:11:"option_name";s:16:"widget_sow-image";}i:2;a:7:{s:5:"title";s:46:"How much heat does the led lamp bead generate?";s:4:"text";s:1072:"The electric power of led lamp bead is more than 65 streams/watt

LED lamps generate a lot of heat, and more than 70% of them are heat. There is little difference between different manufacturers.

If the heat dissipation area of the radiator is large, the temperature will be low when touched. If the radiators are about the same size, it is not good to touch the ones with low temperature, because the heat is accumulated inside and does not come out. LED lights don't last long.

When the LED is working, it has to do work, and when it is lit, it will generate heat when the energy is converted. The greater the power, the stronger the work, and the greater the heat generation.

Poor quality LED lamps, because the current is unstable, cause a rapid temperature rise and are easy to burn out. If it is a car light, it should be considered whether the voltage fluctuation is too severe. For example, the output voltage of the car generator is high, and the decoupling filter circuit is poor.
